I hope the WW works out for him, but being an old school type of person, I am very leery of any "snake oil" additive. I figure if it worked, then the manufacturer woud recommend or use it. The only additive that I know works in a modern EFI motor is Techron.
I've seen and tried for fun a bunch of these miracles in the can from
Slick50
Duralube
PTFE products
Zmax
MMO
SeaFoam
Motor Honey
STP
and so on.
MMO does work on motors to free up rusted parts and clean out sludge, but I wouldnt use it on an engine that ran well.
